Hello,

Looking at the provided screenshot I do believe you are using mininet.

If the above is true, did you try to issue the "pingall" command from the mininet cli?

this should result in hosts generating traffic and being dicovered by the controller.

On the other hand I noticed as well that you:

1) installed the GUI on the server

2) I suspect you installed mininet on the same server.

HP support suggest not to install the GUI on the controller server (you can access the controller GUI from another device) and also NOT to run mininet from the same machine (but rather installing it on a different device on same lan).

I hope the above helps you in solving this issue,

Regards,

Hi, I assume too that you are using Mininet. Mininet works best when the controller is in pure OpenFlow mode. By default, the HP Controller is in Hybrid mode. To change it, go to Configurations - com.hp.sdn.ctl.of.impl.ControllerManager and change the "hybrid.mode" settign to false. Then restart the SDNC service.
